CUTTING AND PRINTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 609,007, datedAugust16, 1898. Application filed December 15,1396. smart, 615,735. (Nomodet)To all whom it may concern:

Be it known that 1, WILLIAM H. BUTLER a citizen of the United States,residing at Harrison, county of Westchester, and State of New York, haveinvented certain newand useful Improvements in Cutting and PrintingMechanism, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.The object of the presentinvention is to provide an improved cutting andprinting mechanism for cutting portions from a strip of cardboard orother suitable material and printing on the strip, the constructionbeing especially adapted for forming box-blanks from a strip of materialand for attachment to-boX-making machines, packing-machines,

and similar machines by which box-blanks are formed into boxes, eitherwith or Without filling, although it will be understood that my improvedconstruction may be used also either asa separate machine or combinedwith other mechanisms for acting on a strip of suitable material forother purposes.

As a full understanding of the invention can best be given by a detaileddescription and illustration of aconstruction embodying the same, such adescription will now be given in connection with the accompanyingdrawings, showing a construction embodying all the features of theinvention in their preferred form, and the features forming theinvention then specifically pointed out in the claims.

In the drawings, Figure 1 is a side view of the construction. Fig. 2 isa plan view, the frame being sectioned on the line 2 of Fig. 1. Fig. 3is a vertical section, on an enlarged scale, looking to the left fromthe line 3of Fig. 1. Fig. 4; is a central longitudinal section of thecutting, feeding, and printing de= vices on the same scale as Fig. 8.Fig. 5 is a cross-section looking to the left on the line 5 of Fig. 4t.Fig. 6 is a detail side View of the ductor and fountain roll and theiractuating devices.

Referring to said drawings, A is the frame, which may be of any suitableform to support the operating parts, B B a pair of cutting cylinders bywhich portions are cut from a strip of material so as to form a strip ofblanks 0f the desired form, and O O are a pair of 'actingwith depressedfeeding-surfaces 13 on the lower roll 0 to feed the portions 0: cut fromthestripin' forming the blanks, these portions xcut from the strip beingguided downward away from the strip and delivered from the machine bythe curved'guide 14:.

The segments 12 are of such height as to assure the separation of thecut portions w" from the body of the strip w and their proper deliveryby the guide 14 by positively depressing the leading ends of theseportions to the proper side of the guide 14.

The strip a; is shown as fed to the cutting rolls l3 Bfrom a web-roll X,supported in the upper part of the frame, the strip passing around theguide-roll 16 and between side guides 17, so as to be deliveredaccurately to the cutting-rolls B B.

1 Beyond the feeding-rolls O G the stripe: of blanks passes over asupport 15 above the guide 1e and then to the printing devices,

Which in the form shown consist of the type and impression rolls D E,the type=roll D be- 1 ing shown as carrying a single printing-plate (1,although two or more plates may be used for a plurality of impressionsto each rotation of the rolls. The impression-rollE carries one or moreimpression-blocks b,of rubber or similar yielding material, so that therolls may be positioned for a heavy impression without danger of injuryto the printing-plate if the machine be run without a strip in it. Theplate! is inked from a form-roll F, supplied with ink from a supply-rollG, coacting with distributing=roll H and taking ink from the ductor-rollI, which moves between the supply roll G and the fountain-roll J,running in the fountainK. I

' For the proper distribution of the ink on supply roll G, in connectionwith the distributingu'oll H, this roll G ismountedto slide upontheshaft 8, by which it is rotated, being shown'assplined to the shaft, andthis roll G carries at one end a cam 19, which engages a roller 1,inserted in a-pin 20 on the frame, so that as the roll G rotates withitsshaft 8 it is moved longitudinally of the shaft by the engagement of thecam 19 with the roller 1 on pin and returned to position by coiledspring 21 on the shaft.

The ductor-roll I is moved between the sup ply-roll G and fountain-rollJ, so as to carry ink from the latter to the former, by the movement ofa block 22, sliding horizontally in a slot in the frame, and in whichthe roll I is mounted, this block being actuated to carry theductor-roll I into contact with the fountain-roll J by lever 23,connected to the block 22 and engaged by an arm on the shaft 8, thislever 23 being pivoted on the frame and returned to position afterengagement by the arm 25 by the spring 26. The block 22 is shown in Fig.6 as narrower than the slot in the frame in which it moves, so as tohave some vertical movement therein, thus permit ting the slightvertical movement of the block which results from the swinging of thelever 23, to which the block is pivoted. The fountain-roll J carriesinside the frame a ratchetwheel 27, and the block 22 is provided insidethe frame with an arm 28, carrying a pivoted pawl 29, which engages theratchet-wheel 27 and thus rotates the fountain-roll J as the ductor-rollI is moved into contact with the fountain-roll J.

The parts may be driven by any suitable means; but in the constructionshown all are driven from the shaft of the roll 0 through suitablegearing, as follows: The rolls 0 C are geared together by gears 30 andthe feedrolls B B by gears 31, the latter being driven from shaft ofroll 0 through intermediate 32. The type and impression rollers aregeared together by gears 33 and driven from the shaft of roll 0 througha large intermediate 34. This intermediate also drives shaft 8 throughgear 35 thereon.

Above the support 15 is a guard or partition 40, under which the strippasses to the type and impression rolls D E, this partition acting toprevent the dust and small particles of material resulting from thecutting and feeding of the cardboard strip from passing forward to thetype and impression rolls, where they would interfere with the printing,and to guide the strip so that it will pass to the type andimpressionrolls properly. The support 15 is shown as formed of a plate providedwith an opening 2 behind the partition 10, through which said dust andlight material will fall, the support 15, with the sides of the frameand partition 40, thus forming a boX through which the strip passes. Itwill be understood, however, that the support 15 may be formed ofseparate bars or in any other suitable manner to support the strip andat the same time permit loose material to pass through. Below thesupport 15 and just behind the type-roll D is a guard 41, extendingdownward a sufficient distance to protect the inking devices from dustand similar light material passing through the opening 2 or carriedforward below the guide 14, the entire printing devices thus being keptclear of such material.

It will be understood that the printing devices will be omitted if thestrip is not to be printed and that the printing devices may be usedalso for printing without the cutting and feeding devices illustrated,so that these two groups of devices form in themselves parts of theinvention, although preferably used together.

By the terms segmental portion and segment, as applied to the projectingportions of one of the feeding-rolls, it is meant that such portionsextend only partially around the roll, so that they may act only duringa part of the movement of the rolls and separate from the stripsuccessive portions cut therefrom, as the portions to, and move theleading end of such cut portions transversely to the strip to the properside of the guide 14 without preventing the feed with the strip of anyparts of the strip that it may be desired to leave between thesuccessive cut portions, and these terms are intended to coversuchprojecting portions even though they do not extend circumferentially ofthe roll, so as to form feeding-segments by which the cut portions arefed longitudinally, as in the preferred construction shown.

What I claim is 1. The combination with devices for cutting portionsfrom astrip of material, of feeding devices for advancing the strip ofmate rial, a guide for directing the portions cut from the strip awayfrom the strip, and means between said cutting devices and said guidefor separating the leading ends of successive cut portions from thestrip and moving them transversely to the strip to the proper side ofthe guide to secure their proper guidance, substantially as described.
